The ide (Leuciscus idus), also known as the orfe, is a freshwater fish of the family Cyprinidae found across northern Europe and Asia. It occurs in larger rivers, ponds, and lakes, typically in schools. The name is from Swedish id, originally referring to its bright color (compare the German dialect word aitel 'a kind of bright fish' and Old High German eit 'funeral pyre, fire').
The body has a typical cyprinid shape and generally silvery appearance, while the fins are a pinkish red in varying degrees. The tail and backfin can be greyish. In older and bigger fish the body color can turn to yellow/bronze.
